About the article xiaobiao before too much about the hot stove knowledge point, many users also from the issue of the article learned a lot, today to bring you what kind of new knowledge point? Presumably many people are not interested in the heating elements of a high-temperature furnace, such as the type of heating elements of a high-temperature furnace? Or high temperature furnace temperature change and the corresponding heating elements have what different place, maybe a lot of people know that the high temperature furnace heating element of some common sense knowledge but also some users don't know, so I could know the user look small make up to tell everyone about you learn from the essence, don't know the user to concentrate on the lecture, however, the following give you something about it.
The first is the type of common heating elements in high temperature furnace
The high temperature furnace has relatively high requirements on heating elements because of its high temperature. There are three common heating elements: resistance wire, silicon carbon rod, silicon molybdenum rod and so on.
And then the high temperature furnace what's the difference between the heating elements depending on the temperature?
Different heating elements of high temperature furnace adapt to different heating temperature. Generally speaking, the high-temperature furnace with the temperature below 1100℃ USES resistance wire for heating, the high-temperature furnace with the temperature below 1300℃ USES silicon carbon rod for heating, and the high-temperature furnace with the temperature above 1300℃ USES silicon molybdenum rod for heating. Special: Si-Mo bar is not suitable for high temperature furnace with operating temperature below 900℃ for a long time, because the characteristics of si-Mo bar will occur low temperature oxidation.
